Specification of Letters Patent.

To will whom, it many concern.-

Be it known that 1, CHARLES FEID, a citizen of the United States,residing at North Attleboro, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement in Methods ofMaking Chains, of which the following is a specifica tion.

This inventionhas reference to an improvement in method of makingchains, and more particularly to rope chains.

The links of rope chains as heretofore constructed are secured togetherby soldering by hand every second link to the next adjoining link afterthe chain is formed. This manual method of soldering rope chainsrequires great skill and is extremely slow in operation, therebyincreasing the cost of rope chains over other forms of chains; also, asthe charge of solder in this method of soldering, particularly in smallchains, is extremely minute, the soldering is often defective, thusrequiring skilled inspection and resoldering of parts of the chain.

The object of my invention is to improve the construction of a ropechain by the use of my new method, whereby a more perfect rope chain isconstructed than has heretofore been done.

A further object of my invention is to improve the method of solderingrope chains.

A still further object of my invention is to reduce the cost ofmanufacturing rope chains.

My invention consists in the peculiar and novel method of constructionof a rope chain, as will be more fully set forth hereinafter and pointedout in the claim.

Figure 1 is a side view of a section of rope chain embodying myinvention. Fig. 2 is an enlarged side view of three links, the centerone of which is charged or covered with solder and illustrating themethod of forming a rope chain. Fig. 3 is an edge view looking at theupper edge of Fig. 2. Fig. 4 is a greatly-enlarged sectional view takentransversely through the chain, showing every third link charged withsolder and the condition of the chain before soldering; and

Fig. 5 is a transverse sectional view similar to Fig. 4, showing thecondition of the chain after soldering.

In the drawings, a 0. indicates the uncharged links, b b the linkscharged with solder, and c c the solder on the charged links, as shownin Fig. 4, for securing the adjacent uncharged links a a to the chargedlinks I) b when fused, as shown in Fig. 5. The uncharged links a a areformed of wire in the usual way, as shown in Fig. 2. The charged linksare formed from a wire (preferably of the same metal as the unchargedlinks) which is completely covered with a thin film of soldier in anywell-known way and fluXed with boraX or other soldering fluid beforeforming the wire into the links. The chain is now formed up in the usualway of the links a a and b b in series of two uncharged links a a andone charged link 6, every third link being a charged link, as shown inFigs. 4 and 5. The completed chain is now subjected to a predeterminedheat and the solder c c fused between the links a a and I), thus firmlysecuring the links of the chain together in series of three links, asshown in l? ig. 5. In practice I find that in this form of soldering thesolder when fused will run entirely off the outer surface of the linksI) b and collect between the link I) and the links a a, thus exposingthe metal on the outer surface of the links I) b and firmly securing thelinks a a to the links I) I), as shown in Fig. 5. Also by solderingthree links together by my new method instead of two by hand, as was thepractice heretofore, a very much stronger chain is constructed.

I do not wish to confine myself to a rope chain, as it is evident thatintermediate links charged or covered with solder could be used in otherforms or kinds of chains without materially affecting the spirit of myinvention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The herein-described method of making chainsconsisting in interposing charged links between uncharged links, andthen subjecting the chain to a predetermined heat which will fuse thecharging of said charged link.

.In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES FEID.
